A light among the gentiles

the long version

"In the past it was commonly thought that Jews were involved in active missionary efforts during the second temple period, but McKnight argues that they were not. Read any discussion about the question of a Jewish mission in the 2nd temple period, and this book by McKnight is usually credited with changing the previous consensus to a new one around his view. So the book is important, and McKnight has worked hard and done his homework in the original sources" -- Amazon.com.
